Body:
I have the same error running XDoclet on a standard java bean that I want to
load into JMX as an XMBean. The process worked well until I tried to set up
notifications. You can't run the JBoss XDT on a class marked up with
@jmx.notification with only the name (and description) attributes set. You also
need to add a notificationType attribute, or you will get the NPE.
As an aside, it would have been much easier for me to diagnose that problem if
I had been able to turn on debugging level logging in XDoclet. After several
hours trying to follow the instructions in commons logging, Ant ant XDoclet I
still can't get it to work. I had to hack the XDoclet class files and use
System.out.println instead...
I expect the problem here is that one or more of the marked up classes use
jmx.notification, although that might not help directly. I can't see why the
XDT should fail on the quick glance I have given it. I can just add the
notificationType which solves my problem.

Status: Open
Priority: Major
Original Estimate: Unknown
Time Spent: Unknown
Remaining: Unknown
Project: XDoclet
Components:
JBoss Module
JMX Module
Versions:
1.2.2
Assignee: xdoclet-devel (Use for new issues)

Description:
When trying to generate an XML descriptor file for a JBoss XMBean I
consistently get an error like the one below. No amount of tweaking the tags
and their parameter produce anything else.
Invoking method failed: xdoclet.tagshandler.ClassTagsHandler.forAllClassTags,
